Title: Game machine
Inventor: NAKANISHI YOHEI
IPC: A63F7/02
Filed: 2019-02-13
Abstract: To provide a technology for maintaining a player's motivation for playing a game.SOLUTION: In a Pachinko machine 1, a background/voice pattern is changed every time pseudo variation performance is executed. Thus, because a background image/BGM is switched as often as the pseudo variation performance is executed while a special symbol varies once, it is possible to show the special symbol as if the symbol varied many times. In the Pachinko machine 1, when changeover performance is executed, a background/voice pattern is changed across performance groups in linkage with the action. A change of patterns among different performance groups is larger than a change of pattern within the same performance group and it is possible to switch contents of the background image/BGM entirely, so that it is possible to draw the player's interest to the game considerably by making the player wonder if some special development may have occurred by making changes as the changeover performance is executed. Thus, it is possible to maintain the player's motivation for playing the game.SELECTED DRAWING: Figure 72
